Normally, when your plumbing is green it's time to call somebody, but when your plumbing is metaphorically green, that's a good thing. The new LEED Platinum-certified Bank of America Tower at 1 Bryant Park features a system that collects rainwater, distributes it to the building's toilets, then filters and reuses the same water. Annually, it saves 13 million gallons. People who know about such things say that green plumbing is an essential part of environmentally sustainable buildings of the future. [Crain's]
